Hi Marcus, sure, you can do that. (put _.str() around the numerical return value of len() ) But I dont think this is what you want here. This way the link would contain: <a href="BASE5"> or something. May be, <a href="/<dtml-var expr="_.string.join(hello.getPhysicalPath(),'/')">/"> .. </a> does what you want.

Hi there,

how do one sum up the values of two variables?

<dtml-let a="_.len(hello.getPhysicalPath())" b="'BASE'"> <dtml-var a> <dtml-var b> </dtml-let>

In other words: the result of _.len(hello.getPhysicalPath()) and the string "BASE" should sum up to one variable, something like

<dtml-let a="'BASE'+_.len(hello.getPhysicalPath())">

Thank you Marcus
